Introduction
The Camaenidae is a diverse family of snails found throughout much of the tropics. The greatest diversity occurs in eastern Asia and the Australasian region. Many species are also known from Central and South America and some Caribbean Islands. Two introduced species, Zachrysia provisoria (Pfeiffer, 1858) and Caracolus marginellus (Gmelin), occur in Florida. These Cuban species were purposefully released in Miami during the early 20th Century by Charles T. Simpson (Clapp, 1919; Pilsbry, 1939). The presence of viable populations of Z. provisoria in south Florida has been recognized for many years. Caracolus marginellus has recently been rediscovered in the Miami area.
